No available desktops after upgrading ESXi

[EddieA]

Hi.  I’m running NoMachine 7.7.4_1 on a Slackware 14.2 system on my ESXi.

Today I upgraded the ESXi from 6.7 to 7.0.  Prior to the upgrade I had to move the Slackware system from one datastore to another using the VMWare web interface, because the RAID card for the original datastore isn’t supported on 7.0.

Following this, trying to initiate a connection from Windows 11, I firstly get the “Cannot detect any display running” as per normal.  However, when selecting “Yes” to create the new display, I’m greeted with:  “No available desktops on this server”.

Other than the underlying ESXi upgrade, there were no changes made to either the virtual Slackware 14.2 or the Windows 11 I connect from, which worked perfectly prior to the upgrade.

Looking in the NoMachine logs, I can’t see anything to indicate an error.

If configuration on that Slackware wasn’t changed, there shouldn’t be a problem with creating the desktop. Are you able to run startx from your virtualization client? If not, that would indicate a problem with image after ESXi upgrade. If desktop started and after sudo /etc/NX/nxserver --restart you’re still not able to connect, please send logs. First enable them, reproduce the problem and then collect logs (more instructions are there: https://knowledgebase.nomachine.com/DT11R00182).

Yes, running startx from the virtual console starts up the KDE session.

Logs attached following an attempt to start a session from Windows.

I’m not trying to connect to an existing session, I’m using the ability for NoMachine to create it’s own.

Also, note that my environment is still configured as per:  https://forums.nomachine.com/topic/still-cannot-find-default-environment-after-tr09n07188-fix

Can you check what shows with whereis "libpam.so.0" command, and htat are you able to log as local user with: /usr/NXbin/nxexec --auth (execute that command as local user, do not use “sudo”).

[EddieA]

Slackware has never used PAM.  Well not until 4 days ago when Patrick released 15.0.

After adding the missing /:

eddie@The-Tardis:~$ /usr/NX/bin/nxexec --auth

what was the output of whereis "libpam.so.0"? It’s not clear if you still have version 14.2 or 15 of Slackware installed. Are you still not able to connect?

[EddieA]

There is no output.  There is no, and has never been any, copy of libpam on a standard Slackware release prior to the 15 released this month.

I’m still testing the latest version, so am currently running both 14.2 and 15.

Cheers.
